Ansible is an open-source automation tool that enables configuration management, application deployment, cloud provisioning, and orchestration.

It uses simple YAML-based playbooks and SSH-based connectivity, making it agentless, highly scalable, and easy to integrate with networking environments.

Commonly adopted in network automation, cloud infrastructure provisioning, and service orchestration as part of modern network design practices covered under CCDE v3.1.

Why other options are incorrect:

B (Contrail): Network virtualization platform, not primarily an automation tool.

C (Java): General-purpose programming language, not specifically designed for infrastructure automation.

D (Jinja2): Templating engine, used inside Ansible but not an automation tool by itself.

FCAPS stands for Fault, Configuration, Accounting, Performance, and Security.

D (Authentication) is not a management category within the FCAPS framework.

Authentication is part of security functions but not a standalone FCAPS category.

Why other options are correct FCAPS components:

A: Configuration management

B: Security management

C: Performance management

E: Fault management

—

Fate-sharing describes a situation where two or more services or components are tied together such that failure in one leads to failure in others. In resilient design, the goal is often to eliminate fate-sharing by decoupling dependencies.

A: A single point of failure (like a shared power supply or converged service path) that brings down multiple components exemplifies fate-sharing.

B is incorrect because fate-sharing is a risk, not a protective measure.

C and D refer to device behavior (stateful inspection, transport layer behavior) rather than architectural dependency.
